STANDARD SPECIFICATIONS FOR 
POWER PIPING 

Adopted by the Power Piping Society June 24, 1915 



GENERAL REQUIREMENTS 



In the absence of a distinct specification by the Purchaser, all material furnished shall conform to 
these specifications. 

It is the intention that all material furnished hereunder shall be of the quality and weight which 
experience has shown to be safe and economical, hence the pressures specified are somewhat under those 
at which satisfactory service can be expected under favorable conditions, but as high as good practice will 
permit. 

In the event of a specification by the Purchaser for service more severe for a given class of material 
than that given herein, such material shall be furnished at the Purchaser's risk, and any guarantees for such 
material made hereunder become null and void. 

MATERIALS 

Castings: All castings shall be smooth and free from injurious defects. 

Cast Steel: The metal in steel castings shall conform to the requirements of the American Society 
for Testing Materials for " Medium Castings." 

Semi-Sieel: The metal in semi-steel castings shall have a tensile strength of not less than 30,000 
pounds per square inch. A transverse test of the "Arbitration Bar," as outlined by the American Society 
for Testing Materials, supported 12 inches between centers shall show before breaking a load of 3,300 pounds 
and a deflection of not less than .12 inches. 

Gray Iron : The metal in gray iron castings shall have a tensile strength of not less than 20,000 
pounds per square inch. A transverse test as for Semi-Steel shall show before breaking a load of 2,900 pounds 
and a deflection of .10 inches. 

DIMENSIONS OF FLANGED FITTINGS 



All standard and extra heavy flanged fittings shall conform to the center to face, thickness, and flange 
dimensions of the "American Standard," as recommended in 1914 by the A. S. M. E. Fittings used for 
working steam pressures 25 pounds and lower, and for water pressures 50 pounds and lower, may be lighter 
in the shell than the American Standard for 125 pounds working pressure. 

DRILLING AND FACING OF FLANGES 

All drilling of flanges shall conform to the templates of the said "American Standard," and shall 
straddle centers. 

Standard flanges shall be plain faced. Extra heavy flanges shall have raised face extending to the 
inside edge of bolt holes. 

SPOTFACING AND BACKFACING 

Flanges of Standard Cast Iron material shall be either spotfaced or backfaced for sizes 30 inch and 
above. All Cast Steel Flanges shall be spotfaced.

(1) Standard and Extra Heavy Reducing Elbows carry same dimensions center to face as regular Elbows 
of largest straight size. 

(2) Standard and Extra Heavy Tees, Crosses and Laterals, reducing on run only, carry same dimensions 
face to face as largest straight size. 

(3) If Flanged Fittings for lower working pressure than 125 pounds are made, they shall conform in all 
dimensions, except thickness of shell, to this standard and shall have the guaranteed working pressure cast 
on each fitting. 

Flanges for these fittings must be standard dimensions. 

(4) Where long radius fittings are specified, it has reference only to Elbows which are made in two 
center to face dimensions and to be known as Elbows and Long Radius Elbows, the latter being used only when 
so specified. 

(5) All standard weight fittings must be guaranteed for 125 pounds working pressure and extra heavy 
fittings for 250 pounds working pressure, and each fitting must have some mark cast on it indicating the maker 
and guaranteed working steam pressure. 

(6) All extra heavy fittings and flanges to have a raised surface of fa inch high inside of bolt holes for 
gaskets. 

Standard weight fittings and flanges to be plain faced. 
Bolt holes to be y§ inch larger in diameter than bolts. 
Bolt holes to straddle center line. 

(7) Size of all fittings scheduled indicates inside diameter of ports. 

(8) The face to face dimensions of Reducers, either straight or eccentric, for all pressures, shall be the 
same face to face as given in table of dimensions. 

(9) Square head bolts with hexagonal nuts are recommended. 

For bolts, 1 % inches diameter and larger, studs with a nut on each end are satisfactory. 

Hexagonal nuts for pipe sizes 1 inch to 46 inches, on 125 pound standard, and 1 inch to 16 inches on 250 
pound standard, can be conveniently pulled up with open wrenches of minimum design of heads. Hexagonal 
nuts for pipe sizes 48 inches to 100 inches on 125 pound, and 18 inches to 48 inches on 250 pound standards, 
can be conveniently pulled up with box wrenches.

as regular straight size elbows and tees. Side Outlet Elbows and Side Outlet Tees, whether straight or reducing 
sizes, carry same dimensions center to face and face to face as regular tees having same reductions. 

(11) Bull Head Tees.orTees increasing on outlet, will have same center to face and face to face dimensions 
as a straight fitting of the size of the outlet. 

(12) Tees and Crosses 16 inches and down, reducing on the outlet, use the same dimensions as straight 
sizes of the larger port. 

Size 18 inches and up, reducing on the outlet, are made in two lengths, depending on the size of the outlet 
as given in the table of dimensions. Laterals 16 inches and down reducing on the branch, use the same dimen- 
sions as straight sizes of the larger port. 

(13) Sizes 18 inches and up, reducing on the branch, are made in two lengths, depending on the size of 
the branch as given in the table of dimensions. The dimensions of reducing flanged fittings are always regulated
